FRESHWATER AVAILABILITY VS. POPULATION GROWTH
We started off with the initial value of fresh water availability for the United States to be 4,477,000,000 m3, and for India to be 500,000,000,000 m3. After these initial numbers, the per capita fresh water use was multiplied by the population and the resulting amount was then subtracted from the overall fresh water available. India’s per capita fresh water use was 1211 m3, and the US ’s per capita fresh water use was 6932 m3 (Census 2004). In order to analyze the increase in water use, we assumed that the per capita water use was the same for all habitants of each country. Per capita water use takes into consideration all the discrepancies and achieves an overall rate. In addition, this graph does not include any excess in-flow of freshwater, which could ultimately affect the rate at which water is used. However, this does not impact the hypothesis being proven due to the growing population, which will ultimately still decrease the amount of available water.
FOREST AREA VS. POPULATION
Deforestation issues arise partly because of the growing masses of poor people who depend on biomass for energy . Furthermore, the migration from rural areas to urban areas has sparked a growing demand for timber, lumber, and paper. Evidently, this rapidly depletes the forests . This loss of forest leads to greater problems since forests have much control over the ecological balance, biodiversity, and quality of the environment. Forests can check for soil erosion, water retention, and conserve and regulate the water cycle. It also retains carbon in order to balance the CO2 and O2 in the atmosphere, thus reducing greenhouse gas emissions . growth forests, and 99% of its tall grass prairie. Every day, an estimated nine square miles of U.S. rural land is lost to development . If we destroy our forests it means that global warming will be even a greater of a problem because of the increase in greenhouse gases. Also, we will lose many animals because they lose their habitat. The food chain will thus be disrupted. So, many countries experience forest loss, but at different rates. The US nears crashes sooner than India because people in the US consume much more wooded products and construction of paved areas is more frequent.
